Abstract
A frequency synthesizer has a fractional Nloop and an integer Nloop. The output frequency of the signal of the fractional Nloop is constrained to values between adjacent harmonics of a reference frequency used in the fractional Nloop. The signal of the fractional Nloop is received by the integer Nloop. The integer Nloop provides an output signal. The output signal can be a high frequency signal such as 2-8 GHz signal.
